Tsheb nyab xeeb - tread qhov tob
Txoj kev nyab xeeb pib nrog lub tsheb nyab xeeb. Tus neeg tsav tsheb zoo yuav tsum paub tias ib qho, txawm tias qhov me me, tsis saib xyuas txog cov txheej txheem ntawm lub tsheb tuaj yeem ua rau muaj qhov tshwm sim loj.
Cov log tsheb tsis tas yuav tau txais kev saib xyuas lawv tsim nyog, thiab lawv yog ib qho tseem ceeb tshaj plaws ntawm koj lub tsheb uas tuaj rau hauv kev sib cuag ncaj qha nrog txoj kev. Lawv cuam tshuam rau kev tsav tsheb kev nplij siab thiab kev nyab xeeb yog li qhov tseem ceeb ntawm kev txiav txim siab. Txawm hais tias lub tsheb zoo thiab ruaj khov npaum li cas, nws tsuas yog kev sib cuag nrog txoj kev yog cov log tsheb. Lawv qhov zoo thiab qhov xwm txheej yuav txiav txim siab seb qhov kev nrawm yuav tshwm sim yam tsis muaj skidding, seb lub log tsheb yuav squeal thaum tig, thiab thaum kawg, seb lub tsheb yuav nres sai sai. Tyre hnav txawv nyob ntawm seb hom thiab hom ntawm cov log tsheb, tab sis nyob rau hauv txhua rooj plaub nws yuav hnav sai dua yog tias siv tsis raug. Cov log tsheb yuav tsum tsis tu ncua los ntawm tus neeg tsav tsheb kom ntseeg tau tias lub siab txaus thiab tshem tawm cov pob zeb me me lossis cov khoom ntse uas nyob ntawd. Kev mus xyuas lub khw log tsheb tsis tu ncua yuav qhia lwm yam teeb meem, xws li hnav tsis sib xws.
Qhov tseem ceeb tshaj plaws yog los xyuas qhov tob tob. Txoj Cai Txoj Cai Lij Choj Txoj Cai Lij Choj tau hais meej meej tias lub tsheb tsis tuaj yeem nruab nrog cov log tsheb nrog qhov tob ntawm qhov tsawg dua 1,6 hli. Qhov tsawg kawg nkaus yog cim los ntawm qhov hu ua cov cim qhia ntawm lub log tsheb. Qhov no yog txoj cai, tab sis koj yuav tsum paub tias nyob rau hauv nag lossis daus tej yam kev mob, muaj kev ruaj ntseg ntau dua los ntawm qhov tob ntawm qhov tsawg kawg nkaus 3 hli rau lub caij ntuj sov log tsheb thiab 4 hli rau lub caij ntuj no log tsheb. Qhov qis dua ntawm tread, dej tsawg thiab slush ntws los ntawm lub caij ntuj no log tsheb. Raws li kev tshawb fawb los ntawm Automotive Industry Research Association tau qhia, qhov nruab nrab ntawm kev sib tsoo ntawm qhov ceev ntawm 80 km ib teev ntawm qhov ntub dej rau cov log tsheb nrog qhov tob ntawm 8 hli yog 25,9 meters, nrog 3 hli nws yuav yog 31,7 meters lossis + 22%, thiab 1,6 mm muaj 39,5 meters, i.e. +52% (kev ntsuam xyuas ua tiav hauv 2003, 2004 ntawm 4 hom tsheb sib txawv).
Tsis tas li ntawd, ntawm lub tsheb nrawm dua, qhov tshwm sim ntawm aquaplaning yuav tshwm sim, uas yog, poob ntawm traction tom qab nkag mus rau hauv dej. Qhov tsawg tread, qhov yuav muaj ntau dua.
- Tsis yog txhua leej txhua tus nco qab tias tsis ua raws li qhov tsawg kawg nkaus tread qhov tob yuav ua rau muaj kev raug cai thiab tus neeg tuav pov hwm yuav tsis kam them cov nyiaj them rov qab los yog them rov qab cov nqi kho mob thaum muaj kev sib tsoo lossis kev sib tsoo yog tias qhov tshwm sim tam sim ntawd yog qhov xwm txheej ntawm lub tread. Peb thiaj li pom zoo kom kuaj tus kheej, zoo dua nyob rau tib lub sijhawm thaum tus tsav tsheb kuaj xyuas lub siab. Ua nws tus cwj pwm txhua hli, qhia Piotr Sarniecki, CEO ntawm Polish Tyre Industry Association.
Tsis tas li ntawd, cov neeg uas tsis tshua tsav lawv lub tsheb thiab xav tias lawv cov tread yog rub yuav tsum tau kuaj xyuas lawv cov log tsheb tsis tu ncua. Yog li ntawd, koj yuav tsum xyuam xim rau tej kab nrib pleb, o, los yog delamination uas yuav qhia tau tias muaj kev puas tsuaj rau lub log tsheb.
Qee qhov xwm txheej, lub tread yuav hnav tsis sib xws lossis pom cov cim ntawm qhov hu ua hnav. hniav. Feem ntau qhov no yog qhov tshwm sim ntawm qhov teeb meem ntawm lub tsheb, tsis raug ncua kev ncua geometry, lossis puas bearings lossis pob qij txha. Yog li ntawd, hnav theem yuav tsum tau ntsuas ntawm ob peb lub ntsiab lus ntawm lub log tsheb. Txhawm rau ua kom yooj yim saib xyuas, cov neeg tsav tsheb tuaj yeem siv cov ntsuas ntsuas, i.e. bulges nyob rau hauv lub grooves nyob rau hauv nruab nrab ntawm lub tread, uas yog cim nrog ib daim duab peb sab, lub log tsheb hom logo, los yog cov ntawv TWI (Tread Wear Index) nyob rau sab ntawm lub log tsheb. Yog hais tias lub tread hnav mus rau cov theem no, lub log tsheb yuav plam thiab yuav tsum tau hloov.
Li cas los ntsuas qhov tsuj tread tob?
Ua ntej ntawm tag nrho cov, nres lub tsheb ntawm ib tug tiaj tus thiab theem saum npoo, tig lub kauj tsheb tag nrho mus rau sab laug lossis sab xis. Qhov zoo tshaj plaws, tus neeg tsav tsheb yuav tsum muaj cov cuab yeej ntsuas tshwj xeeb - lub ntsuas qhov tob tob. Yog tias koj tsis muaj ib qho, koj tuaj yeem siv qhov sib tw, tus pas txhuam hniav lossis tus pas ntsuas. Hauv tebchaws Poland nws tseem yooj yim dua los siv ob lub npib nyiaj rau lub hom phiaj no. Ntxig nrog lub ntsej muag dav dawb hau - yog tias pom tag nrho cov yas, lub log yuav tsum tau hloov. Tau kawg, cov no tsis yog txoj hauv kev thiab yog tias qhov ntsuas qhov tob tsis muaj, qhov tshwm sim yuav tsum tau kuaj xyuas ntawm lub khw muag khoom log tsheb.
